Hi! I'm a fantasy author who has written an urban fantasy trilogy and it's up on Amazon. But it's not selling despite changes to the blurb, category, and keyword. I even spent a little more just to have the book cover for my omnibus. Some say it's an execution problem as in the stories are good but execution is lacking. I don't know what to do and I don't know who to trust. I used a beta reader but had a fallout. I also hired editors. But no matter what I do, nothing seems to stick. I'm crying over this right now.
